PSA: if you install Obtanium, it'll works as an updater for any git repo release apps like this. Just link the source code page and enable "enable prerelease" and it'll download the APK, and it'll check it periodically to run seamless updates. Also Obtainium will update itself from grabbing its own releases from it's git repo page.
It's still in beta but it's fucking amazing. Brings me so much joy to see Infinity live on. I'm using the same theme and settings I did when I use Reddit and it's almost as if I've never left. Just on a better platform now without shitty policies.
